BReflection of equipment located on the opposing wall
CUse of non-tempered glass on the walls
DInadequate overall facility illumination
ELights placed directly over the mirrors
✓ Correct answer: E. Lights placed directly over the mirrorsThe correct answer is lights placed directly over the mirrors. Improper lighting placement relative to mirrors is a common cause of glare that obscures vision. Guidelines suggest that mirrors should be placed to avoid capturing the reflection of overhead lights or windows. Distractor 1 is incorrect because mounting mirrors 20 inches from the floor is the recommended standard (allowing visualization of plates while protecting the glass from dumbbell rolls), not a cause of glare. Distractor 2 is incorrect because reflection from the opposite wall typically provides depth, not blinding glare. Distractor 3 is incorrect because glass type affects safety (shattering) rather than glare generation. Distractor 4 is incorrect because low lux levels would cause dimness, not glare.
